What is the Difference Between Monocrystalline and Polycrystalline Solar Panels? Solar panels take advantage of a powerful yet free energy source - the sun. In a single hour the sun transmits more energy to the earth's surface than the world uses in a year. Our guide outlines how you can use solar panels to make use of this free source of energy to generate electricity and hot water for you home. Types of solar panels The two main types of active solar panel systems are Monocrystalline Panels ,Polycrsytalline Panels (also known as multicrystalline) The differences between these two types of solar panels relate to the manufacturing process rather than product characteristics. Monocrystalline solar cells are produced from a single crystal of silicon while polycrystalline solar cells are produced from a piece of silicon consisting of many crystals. Monocrystalline Panels The solar cells in monocrystalline panels are slices cut from pure drawn crystalline silicon bars. The en

If you are moving from a utility-connected home in the 'burbs' to an off-grid home in the boonies, you will have the opportunity (perhaps necessity) of downsizing your electricity usage. In order to calculate how large your home power system needs to be,  run the calculator to check . Compare and adjust your plans according to your budget and lifestyle. Please also refer to the daily sun hours in USA if you are USA customers, other customers from outside the coutries, please check the daily sun hours in your coutry.  Run the  System Sizing Calculator   first with numbers from your current electricity usage. You can aslo refer to  the eletric appliance power consumption chart (PDF) , The daily energy values listed in the PDF file are for the most efficient units in their class and the information was obtained from Consumer Guide to Home and the General Electric website. Use the power consumption to calculate the power you will need.  These figures are approximate an

Solar (or photovoltaic) cells convert the sun’s energy into electricity. they rely on the the photoelectric effect: the ability of matter to emit electrons when a light is shone on it. The solar cells are made of silicon and other materials which made up of at least 2 semi-conductor layers, one layer called P layer with extra electrons, another is called N layer missing equivalent electrons.  When the sun shines on the solar cells, free electrons from the P layer flow to N layer. Then it forms the electrons current. When the sun shines on the solar cells, the sun will realize photons, which contains sun energy. Many of the photons are reflected, pass right through, or absorbed by the solar cell. As these  hit the silicon atoms of the solar cell, they transfer their energy to loose electrons, knocking them clean off the atoms. The photons could be compared to the white ball in a game of pool, which passes on its energy to the coloured balls it strikes. E lectrons are freed f

Wind Energy Wind is a form of solar energy . Winds are caused by the uneven heating of the atmosphere by the sun, the anomaly of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover. This wind flow, or motion energy, when "harvested" by windturbines , can be used to generate electricity . Societies have taken advantage of wind power for thousands of years. The first known use was in 5000 BC when people used yacht to sail the Nile River. Persians had already been using windmills for 400 years by 900 AD in order to pump water and grind grain. Windmills may have even been developed in China before 1 AD, but the earliest written documentation comes from 1219. Cretans were using "literally hundreds of sail-rotor windmills to pump water for crops and livestock." Wind Energy Sources Today, people are realizing that wind power "is one of the most promis

On Grid or off Grid Firstly, we should probably explain just what a grid is. A grid is a network that supplies electricity to consumers. Nothing is too complicated - it's the vehicle which supplies electricity to businesses and residences. But what’s the difference between on-grid and off-grid? Before you make decision, let’s take a closer look at the pros and cons. On grid Solar System On-grid solar systems allow you to connect your solar panel system to the electrical grid. Electricity generated by the solar panels is put into the grid during peak production. It is stored and then recovered whenever needed. On Grid systems do not require a battery, because the grid acts as the battery. With "net metering", the utility meter spins backwards and credits the solar system owner for their energy production to keep track of it.  Advantage Using renewable energy on the grid avoids most, if not all, the disadvantages of being off grid. The utility is like

                                        Solar Panels for Homes Are you interested in building your own solar system to save cost? Do you know nearly 75% of the cost goes to professional installation? Imagine saving so much money by yourself. Please go on reading this article if you like it! Solar panels make use of solar energy to generate electricity. It will provide energy inside the houses and offices. They are useful sources of energy, especially when you find yourself relocating in somewhere without any possible to obtain commercial electricity. All you just need to do is to buy some solar cells, and please make sure each cell’s voltage is measured, so that they can provide you enough electricity. Solar panels for homes will be beneficial to you in a lot of ways. Not only you will reduce the carbon but also save your electricity bill, and you can even sell some of the excess power to electric company if you live in Australia. I know there are a lot of people who d
